Change in reciprocity as a predictor of depressive symptoms: a prospective cohort study of Finnish women and men.

The purpose of the study was to examine gender differences in the association between changes in the balance of give and take in close relationships and depressive symptoms. Data from a 5-year prospective cohort study in Finland (HeSSup Study) (N=18,445) were analyzed. After adjustment for demographic characteristics, recent negative life events, baseline depressive symptoms, hostility, and the supportiveness of social network, a shift of balance toward support receiving was a significant risk factor for future depressive symptoms among women. In contrast, men whose balance of give and take had moved toward support giving had a higher risk of future depressive symptoms than other men. When the analyses were replicated in a sub-cohort of initially non-depressed participants who lived in reciprocal relationships and had no recent life events, the results became even more pronounced among women, although not among men. We conclude that, for women, a shift in their close relationships toward support receiving may lead to increased risk of depressive symptoms, whereas for men a shift toward giving may have a parallel though less evident impact.
